The T helper cells (Th cells) are a type of T cell that play an important role in the immune system, particularly in the adaptive immune system. They help the activity of other immune cells by releasing T cell cytokines.These cells help suppress or regulate immune responses.hey are essential in B cell antibody class switching, in the activation and growth of cytotoxic T cells, and in maximizing bactericidal activity of phagocytes such as macrophages. Mature T h cells express the surface protein CD4 and are referred to as CD4+ T cells.

Lately, I've been cutting beef chuck roasts into small pieces before boiling in my pressure cooker which makes eating at work for lunch more convenient (no knife & fork need at lunch). It's really delicious! Can I (should I) cut the pork before cooking? (or cook it whole)? I cooked the 3 pounds of cut up beef for 30 minutes in the pressure cooker. Any guesses on how long to cook the pork? It's 11pm Tuesday, and I'll be cooking this tomorrow morning (6am) so if you have an suggestions for this first attempt, I'd certainly appreciate it. Thanks, Mike
